I do not have the switches and I can see how that would have kept me from
my problem. I will do as you suggest and get a hold of Alex for the new
improved version. Thanks for the info!

My Strong pitch servo has NC micro switches at each end of the screw.
When you get near the end of travel, power is removed from the servo,
thus you never bump up against the end of travel on the physical screw.
I can hold the switch down in either direction forever and it would
never cause any problems.
Does you servo have these switches?
My advice is to take a picture of the servo and send it to Alex. See if
he would recommend changes to the unit. Alex has been more than helpful
for my installation.
